Setting our minds to implementation

It is now well accepted that to prevent sports injuries we need more intervention studies. Therefore, it is somewhat alarming that most sports injury studies still only focus on the fi rst two steps of the four-step prevention sequence of van Mechelen et al: only counting injuries and describing causal factors. This has clearly been shown by Klügl et al, who reviewed approximately 5274 original sports injury publications, of which only 492 studies intended to establish the preventive value of a measure or programme. This review showed that although the number of efficacy/effectiveness studies has slowly increased over the years, this is still lagging behind the approximately 4000 descriptive and aetiological studies.
